We’re assuming it because that’s exactly what has happened with other products in the past. It’s an issue the field has struggled with, so it seems likely.
Maybe I'm not aware of what you're referring to, but I don't think so. I think, like this incident, companies apologize for stuff like this because they lack the courage to say the truth, which is that it's an unfortunate labeling error but not a big deal. Instead, they judge it to be more political to beg forgiveness. Of course, the people who get offended by labeling errors are only encouraged by apologies and use them as evidence of wrongdoing.
